Question

Type the missing number to complete the proportion. 86 chairs in 2 rows = chairs in 1 row Submit

Answer 1

hello

from the question given, we have

`\begin{gathered} 86\text{chairs}=2\text{rows} \\ x\text{ chairs= 1 row} \end{gathered}`

cross multiply both sides

`\begin{gathered} 86\text{chairs}=2\text{rows} \\ x=1 \\ 2* x=86*1 \\ 2x=86 \\ \end{gathered}`

divide both sides by 2

`\begin{gathered} (2x)/(2)=(86)/(2) \\ x=43 \end{gathered}`

from the calculation above, we have 43 chairs in 1 row
